One of The Twelve Swords

The Sword of Justice
Symbol: a circle

Doomgiver will redirect all attacks against its possessor back against the attackers. Some instances of this phenomenon include arrows flying in a complete circle to strike those who had launched them.

The Sword of Justice balances the pans
Of right and wrong, and foul and fair.
Eye for an eye, Doomgiver scans
The fate of all folk everywhere.
